The method involves correcting a non-linear phase error of an amplitude detector via a look up table (LUT) that is driven by a radio frequency (RF) signal. The LUT provides values that are usable to correct an RF output that is a function of the RF output signal and is not a function of a device that incorporates the open loop modulation system of the present disclosure. Specifically, a detection of the corrected RF output amplitude is usable to drive a phase correction so that the RF output with corrected phase is a function of the RF output alone and not a function of a system or circuit that generates the RF output signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Polar feedback linearization","description":"A system and method for providing a polarization feedback linearization to correct a non-linear amplitude error of an amplitude and phase detector or polar detector is disclosed.
